A Few Questions about the 300D 2.5 Turbo
I had a few questions about the 1991 300D 2.5 Turbo.
Here of late my family has been considering purchasing a '91 300D 2.5 Turbo...I had a few questions about it.
I have heard in general that is is a really good car, and that, in general, I will not have to worry about much maintenance.....except for failure of the AC eventually.
I am considering using home-brew BioDiesel in this vehicle, and was wondering if it will need any modifications? I know BioDiesel is extremely clean, and can dissolve certain rubber seals....and I was wondering whether or not this particular car would need those items replaced or not in order to safely run BioDiesel....

Ok
When I say home-brewed biodiesel, I mean REAL biodiesel.....Waste Vegetable oil that has been filtered, properly heated, mixed with methanol, and lye....also washed, etc.
At first I was considering a straight vegetable oil system until I read all that you had to do to modify the car.
I have read that all one must do is replace all the seals with viton, and change out the fuel filter until the car is completely clean...Would you happen to have any further information on this whole process? Thanks.

And just for the record, I've recently found out you don't need the expensive viton hose. Regular brand new fuel line does just fine with biodiesel. The reason you see so many fuel line failures using biodiesel has to do with the age of the hose, not the material it's made from.
